Boumediene v. Bush

Congress passed the Detainee Treatment Act (DTA) in 2005 to create procedures letting Guantanamo Bay detainees challenge their classification as unlawful alien enemy combatants, then passed the Military Commissions Act (MCA) in 2006, whose § 7(a) barred those detainees from challenging their detention through habeas corpus at all. Boumediene (plaintiff) and other detainees sued to challenge their detention via habeas corpus; the D.C. Circuit upheld the MCA's constitutionality, and the detainees petitioned for certiorari (the Supreme Court's discretionary agreement to hear a case).
